12" 223 Remington for Contender/G2
4-hole Scope pattern, rear placement
NOTE: This barrel has been chambered to tight tolerances and should only have virgin components or ammo used. Remanufactured (even if full-length resized) or once-fired brass from another manufacturer's firearm is not recommended and will either not fit, or will cause a pressure issue and bend your extractor. Call with any questions.
